On 27 October 2006 a subsidiary sold its interest in a joint venture, Copperbelt Energy Corporation plc. The joint venture investment was classified as an asset held for sale at 31 March 2006.

Trade receivables are non interest-bearing and generally have a 30-90 day term. Due to their short maturities, the fair value of trade and other receivables approximates to their book value. Asset held for sale is recorded at fair value. All other receivables are recorded at amortised cost.

The carrying amounts of trade and other receivables are denominated in the following currencies, which in most instances are the functional currency of the respective subsidiaries. Our exposure to US dollars forms part of our net investment in our US subsidiaries which is further described in note 23 (a). We do not have any other significant exposure to currency risk on these amounts.
